http://momjian.us/main/writings/pgsql/sgml/view-pg-timezone-names.html says
that the names in the view are "recognized" as argument to "SET TIMEZONE".
However some of them can still not be used if they contain leap seconds, try
for example

set timezone to 'Mideast/Riyadh87';

Should we just document that some can't be set or remove those from the view
completely or add another boolean column has_leapsecs or similar?

Removing them seems not to be the right idea because you can say:

select now() at time zone 'Mideast/Riyadh87';
